Specification of Letters Patent;

Patented July ib-3, 1915 Application filed. March 19, 1915. Serial No.15,480.

To all whom z't may concern:

Be it known that I, JOHN BROUWERS, a citizen of the United States of.America, residing at Sparta, in the county of Kent and State ofMichigan, have invented certain new and useful Improvements in Furnaces; and]: do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to furnaces, and it is an object and purposethereof to provide new and improved constructions in furnaces whichpermit the ready assembling of the furnace with a minimum of trouble andexpense.

It is a further object of the invention to provide means dividing thechamber in which air is heated in the furnace into a plurality ofcompartments from which heated air must escape through an associatedfurnace pipe leading to a room in the house heated by furnace, wherebythe pipes of shortest length in the furnace do not pass practically allof the heated air While the longer pipes pass but very little to therooms with which they are connected.

Still further objects consist in the provision of a furnace locatedhorizontally and having a new and improved construction dividing thebody thereof into a fire box with an ash pit below it, While the upperportion of the body is divided from the fire box to produce a passagewayto the chimney whereby all the products of combustion are brought intoclose contact with the air heating chamber so that the heat from saidproducts may be given off, in a great measure before reaching the outletchimney.

Various other objects and purposes con-Y sisting of a pivotally mountedbaffle wall for controlling the draft and in guard members keeping thefire in the furnacefrom the walls of thebody to prevent its burning out,will be apparent as understanding is had of the construction shown inthe accompanying drawings, in which:

Figure 1 is a front elevation of the furnace. Fig. 2 is a verticalsection taken transversely thereof. Fig. 3 is a vertical section takenlongitudinally of the furnace. Fig. 4 is a front elevation of the gratewith the guard members applied thereto; and Fig. 5 is a plan view of thegrate, the guard members being shown removed from one side of 'for thepurpose of illustration.

said grate. Fig. 6 shows a view similar to Fig. 3 of the front part of amodified form of furnace construction.

Like reference characters refer to like parts throughout the severalviews of the drawings- In the construction of the furnace a cylindricalbody is formed including a lower semi-cylindrical half 1 which, at itsedges, is turned outwardly to form horizontal flanges 2', and at itsfront and rear having integral flanges 3 and 4 projecting verticallytherefrom. The body is completed by an upper semi-cylindrical half 5which, at its edges has outwardly extending flanges 6 adapted to seat onthe flanges 2. Flanges 2 and 6 are connected together forming an openended cylinder. The member 5 is further provided with the inwardlyextending horizontal flanges 7 opposite flanges 6 and at its front andrear edges with outwardly extending flanges 8 and 9 completing, with theflanges 3 and 4, heretofore described, bearing rings towhich the frontand rear of the furnace may be secured.

The front of'the furnace indicated at 10 is detachably attached to thebody thus formed by means of bolts 11 through flanges 3 and 8 and in thesame manner the back 12 is attached by bolts 13 to flanges 4 and 9. Ifdesired the front and back may be extended laterally to each side andalso above the cylindrical body to form a boundary for the chamber,saidchamber being completed by sides 14 connected by a top 15. In thetop a plurality offurnace pipes 16 are secured serving as conduitstoconvey heated airfrom the air chamber to rooms of the house in whichthe furnace is installed. A. cold air inlet passage 17 may be enteredinto the air chamber in any convenient manner, the one shown in thedrawing being merely It is of course apparent that the front and back 10and 12 need not be extended to form the front and back of the airchamber but that the thin metal like that forming the top may be used toform the front and-back of the air chamber while the front and back 10and 12 need extend only to the edge of the flanges 3, 4, 11 and 13 asshown at 10 in Fig. 6, this construction howevergnot changing anyprinciple of operation.

Previous to the connection of the front 10 to the cylindrical body, abaiiie 18 having a curved outline and provided with a back 19 formed asa segment of a circle is introduced into the body by sliding it inwardon the flanges 7 Baffle 18 is secured to the front 10 by means of bolts20 to hold it rigidly in place. When so positioned the back 19 islocated a distance in front of the back 12 of the furnace and the top ofthe baffle is positioned a distance below the top of the cylindricalbody previously described. A grate 21 of any approved construction issupported a distance above the bottom of the lower member 1 and at itsrear end carries a baffle wall 22 hinged to a rod 23. An operating rod24 is connected to the bafile wall and extends rearwardly through theback 12 and has a series of notches 25 cut therein on its undersidewhich engage with the lower edge of the opening through the back. Rod24: terminates in a handle 26 by means of which it may be manuallyoperated to position the baffle wallin various positions with respect tothe grate.

The back 12 has an o ning therein nor mally closed by a door 2% at theupper portion of the body, while another door 28 closes an openingadjacent the lower portion of said cylindrical body. Similarly the front10 has an opening therethrough normally closed by a door 29 directlyabove the member 18 and two doors 30 close openings in the front 10which lead into the fire box formed by the grate 21 and the baflie 18.Below the grate 21 an opening is formed in the front 10which is closedby the doors 31 through which access may be had to the ash pit locatedbelow the grate. Near its forward end the upper member 5 of thecylindrical body has an opening and a pipe 32 is connected to saidmember 5 in conjunction with this opening to carry away the products ofcombustion.

The air chamber formed between the cylindrical body and the outerinclosing members 14 and 15 is divided in its upper half by a pluralityof vertical partitions 33 which on their lower edges are cut to fitclosely against the upper half 5 of the cylindrical body and rest on theflanges 6 thereof, being formed at their outer edges to fit closelyadjacent the inclosing members 14 and 15 of the air chamber. Thesepartitions are positioned between the furnace pipes 16 and divide theupper half of the air chamber into a plurality of compartments fromwhich any escape of air must be through its associated pipe 16 as willbe readily understood. Instead of pipes 16 extending vertically from theair chamber at the central portion thereof as shown in full lines it maybe desirable to have a larger number of pipes, especially with largersizes of furnaces, and these may be positioned at an angle to the top 15as shown in dotted outline at 34 in Fig. l and each of the compartmentsbetween partitions 33 may be further divided by a vertical partitionwall 35 so 7 that each pipe 3 1 will have connection with guards 38which at their lower ends are detachably seated in the openings. Theseguards form a substantial barrier between the fire and the sides of thebody preventing the fire from contacting with and burning through thebody as would otherwise occur, while any guard 38 that becomes burned soas to be useless may be removed at will and a new one used in its stead.

Nith a' furnace thus constructed it will be apparent that products ofcombustion are carried over the bafile wall 23 and under the back 19,passing between it and the back 12 of the furnace and thence forwardbetween the baflle l8 and the top of the cylindrical body to the chimney32. The products of combustion thereupon come in contact with the upperportion of the cylindrical body practically its entire length and heatgiven off therefrom will heat the air in the air chamber of which theupper portion of the body forms one boundary. The heated air passes outthrough the furnace pipes 16 or 24: and it is impossible for the air inone compartment to escape except through its associated furnace pipe.This construction is very easily made and quickly assembled. The upperand lower members 1 and 5 of the cylindrical body are readily cast as isalso the front and back and the bafiie 18 together with the grate andthe guarding members 36 and 38 associated therewith. The assembling ofthe baflle 18 in the furnace is especially simple and effective. Thereare no parts outside of the grate and guards 28 that are liable tobecome useless and these may be readily replaced at any time. The bafliewall 22, by reason of its adjustable relation to the grate, may be swungto vary the passage of the products of combustion from the fire box oversaid wall and adjusted to conform to the particular circumstances underwhich the furnace may be used, while the location of the doors 27, 28and 29 permit a very ready cleaning of the furnace at any time withlittle or no attendant trouble.
